Specialization ofTransformConverterfor UE::Math::TMatrix. Calls ToMatrix() by default. Allows custom types to easily provide support via a ToMatrix() overload or a ToMatrix() member function. Uses decltype to support efficient passthrough of classes that can convert to a UE::Math::TMatrixwithout creating a new instance.
